Rick Kennedy had seven display cases at the Springfield show public exhibit. Below is his introduction, as stated in one of his exhibits:
I've been a collector ever since I was able to pick up with my hands. I've collected everything from stamps and coins to bottle caps. Minerals and rare gemstones became my passion for several reasons: their natural beauty, the fact that I could never learn everything about the hobby and the adventures involved in collecting these beauties in the field.
I received my BS degree in Earth Sciences from the University of California, Santa Cruz in 1994, seven years after finishing my course work (it is a long story!). I started Earth's Treasures in 1985 as a part time business while I worked managing a small business for one of my mineral collecting partners. In March 2006, I left that world for good and became a full time mineral and rare gemstone dealers and have never been so happy!
Personally, I collect "rough and cut" suites of rare gem minerals, but my passion will always be for Benitoite, and I proudly flaunt my status as a poster boy for the Benitoite Mine Run sales that John and Steven did a few years ago, my 5.96 carat flawless cut Benitoite is indeed the "Jewel" of my collection.
Pictured below are all of Rick's public showcases, as well as some individual minerals from within those cases.
